I've stayed at the MArriot in YOrk for many years now - in late January and late July. This year, I was severely disappointed to find that my room was boiling hot all evening - the hotel does not have any air con; I asked for a big fan, and got one quite quickly, but it was quite inefficient - had a very sweaty night, as did my daughter on the sofa bed. I especially asked for a room with 2 beds. We got another fan for the second night, which was a bit more efficient, but again an unsatisfactory night's sleep - too hot. The windows are security locked, and only open about 2 inches. Plus our bathroom had no windows at all, so even more stuffy !!
Will ahve to re-think where we stay next time.
